Description
Lamp design concept, but ready for laser cutting and manual assembly......modeled by parametric means using Grasshopper (Rhino 3d plugin)it calculates the aperture of faces using the desire lux intensity and type of light source

This is a lovely idea! The only thing that strikes me as strange about it is that typically you would want more light to shine out of the bottom of the lamp, but yours releases the most light at the top.

yeah....but its parametrically driven....if you want more lux comming from above the lamp you just order it that way and the apertures will close down (using a mathematical function) as they close to the top of the lamp
you can drive the diameter of the lamp, the lux amount, relative size of apertures and number of facets

That's pretty cool.

I pride myself on being able to recognize a variety of polyhedra. But I have to admit I have no idea what this is.

this is constructed by sampling random points on a sphere,placing a 2d plane normal to the surface of the sphere on each point and then computing the intersection between planes.....
and you can unroll the planar faces for cutting

Interesting!
I notice a line extends from the corner of each hole. So If the holes weren't there, each polygonal face would be be composed of several coplanar triangles?
Do the lasers cut 90 degrees to the plane or are the edges mitered to make the dihedral angle?

yes, all the faces are planar and can be constructed by triangles..i just scale down the face hole to its minimal planar area (zero) and that's it..
i've done another lamp shade composed of only tris, ready to assembly too..
and the laser cuts in nearly 90°, you notice the deviation with materials over 6mm or so.......i'm doing test to position the light bulb, different hole size and number of faces change the center of gravity and for these test i'm using wooden veneer which is 0.5mm....so the laser cut angle tends to go to zero
